Radio frequency
energy harvesting

Do you want your device to recharge from RF source without the need to change a battery? Then, discover our RF Ambient Energy Manager working with external matching network

Is radio frequency energy for you?

Let’s assume you develop battery-powered loT wireless device(s) that operate in environment where they could be charged by RF transmitter

You (or you customers) need to re-place the batteries of those devices, because they run out of energy. This generates operational costs & negative impact on environment

Using dedicated emitters emitting power at 868MHz (Europe), 915MHz (USA) or 2.4GHz, your devices can be powered up
